With more than half of the nation’s 623,218 bridges experiencing significant deterioration, this process is positioned to be a cost-effective, minimally disruptive solution. The technique called cold spray can extend the life of beams, reinforcing them with newly deposited steel. This research was in partnership with the MIT Mechanical Engin
